The study was performed to find the cause of high concentration of BOD and algal bloom during winter season at Mulgum in the downstream of Nakdong River since 1995. There was high correlationship between BOD concentration and Chl. a contents which shows that algal bloom makes Autochthonous BOD. The dominant algae during of winter blooming season was Stephanodiscus sp.. This algae maintained the blooming under the condition of low water temperature, long retention time with decrease of flow rate, and abundant nutrient concentration. To reduce the amount of Stephanodiscus sp. biomass, it is important to decrease the loading of TP and TN from the upstream, because of the possible approach to control.

합성유기화합물의 환경중 운명을 예측하기 위해 많은 평형분배모델과 동적모델이 제안되어져 있는데, 평행분배모델에 가장 중요한 인자인 생물농축계수와 흡착계수를 Benzenhexachloride(BHC)를 대상물질로 실험을 하였다. 향어(Cyprinus carpio)에 대한 α, β, γ-BHC의 생물농축계수는 각각 146, 195.3, 185.6으로 상관관계식에서 구한 α-BHC 153~875, β-BHC 149~185, γ-BHC 138~778와 비교해 보면 하한값에 가까웠다. 흡착계수를 구하기 위해 kaoline, 낙동강 하류 저질, 마산만 저질을 사용하였는데 kaoline에 대한 α, β, γ-BHC의 흡착계수는 각각 201.6, 200.2, 213.5 그리고 낙동강하류 저질에 대해서는 각각 51.6, 49.1, 45.8 이었으며 마산만 저질은 각각 1,389, 2,282, 1,295이었다. 이들값은 상관관계식으로구한 Koc(or Kom)와 비교해 보면 매우 높은 값으로 나타났다. 이상과 같이 생물농축계수는 상관관계식으로 구할 때 범위가 커 선택의 어려움이 있고 흡착계수는 상당한 차이를 보여 분배모델의 정확도를 높이기 위해서는 중요인자인 분배계수를 실측하는 것이 바람직하다. Many equilibrium partition or kinetic models have been proposed to predict the fate of Synthetic organic compounds in the marine environment. Important factors in equilibrium model, such as bioconcentration factors and sorption coefficients were determined by indoor experiments with Benzenhexach1oride(BHC). For α, β, γ-BHC, bioconcentration factors of the carp, Cyprinus carpio were 146, 195.3, 185.6, respectively. For α, β, γ-BHC, sorption coeafficients of the kaoline were 201.6, 200.2, 213.5 and of the Nakdong estuary sediment were 51.6, 49.1, 45.8 and of the Masan bay sediment were 1389, 2282, 1295, respectively. Campared with calculated values by correlation equations, bioconcentration factors were similar and sorption coefficients were high.

The performance of the stormwater wetlands can be significantly influenced by antecedent stormwater in storage at the commencement of a stormevent. As inflows are intermittent and stochastic in nature, the evaluation of the treatment efficiency of a stormwater wetland should be considered by runoff capture and water treatment characteristics during interevent periods. In this study, analytical probabilistic model is applied to identity runoff capture rate and treatment efficiency of the stormwater wetland. To achieve this, continuous rainfall data recorded in Busan for 31 years has been analyzed to derive the runoff capture rate, and 1st order kinetic decay constants (kv, 1/d) are calculated from regression analysis to identify pollutants removal during interevent periods. The results show that about 60.9% of annual average runoff is captured through the stormwater wetland. The annual average treatment efficiencies of SS, BOD, COD, TN and TP is about 11.4, 8.9, 9.8, 4.3 and 9.6%, respectively. The analytical model has been compared with the numerical model and it shows that analytical model is valid. Performance evaluation methods developed in this study has the advantages of considering characteristics of rainfall-runoff, facility type and pollutant removal.

The increase of population and industrial activities had brought into eutrophication in the Nakdong river. A remarkable acceleration of eutrophication brought about serious problems for water supply. Therefore, for the purpose of conservation of water quality in the Nakdong river it is necessary to control nutrients. MBOD method was used to evaluate algal growth limiting factor and algal growth potential in the Nakdong river from June to August 1994. The modified biochemical oxygen demand(MBOD) depends on the amount of available inorganic nutrient and organic substrate during 5 day incubation in the dark at 20℃. The MBOD assay depends on inorganic nutrients such as P and N as well as reduced carbon and called the MBOD, the MBOD-P, and the MBOD-N, respectively. The results of bioassay by MBOD(Modified BOD) method showed that the MBOD, MBOD-P and MBOD-N value were found to be in the ranges of 3.8∼96.0 ㎎O_2/ℓ, 5.6∼94.0 ㎎O_2/ℓand 42.0∼220 ㎎O_2/ℓ, respectively. And the the bioassay value was found to be the highest in Koryong area and the lowest in Waekwan area throughout the Nakdong river. The variations of MBOD-P and MBOD-N value showed similar tendencies to the variations of phosphorus and nitrogen value, respectively. By MBOD method, the relationships of MBOD, MBOD-P and MBOD-N value were MBOD ≒ MBOD-P ≪ MBOD-N. The MBOD value was nearly equal to the MBOD-P value, and the MBOD-N value was 3 to 20 times more than the MBOD-P value, approximately. Therefore, in the Nakdong river, phosphorus was the limiting factor for algal growth during summer season. The algal growth potential as the concentration of chlorophyll-a in the summer was maximum 5 times more than standing crop as it.

Pusan has experienced some different paths of urbanization and industrialization compared to other cities, and has faced the problem of over-saturation in environmental capacity. Pusan needs to find out sustainable development strategies based on Agenda 21 by UNCED in 1992 to secure urban renewal. Therefore, Pusan's sustainable development strategies focus on the 1)research on environmental capacity and reasonable population accommodation 2)supply of basic environmental facilities for the human settlement 3)protection and efficient management of environmental pollution 4)saving and control of energy and other resources 5)independent and stable execution of plan based on biological relation 6)harmony between nature and urban spatial organization. In addition, these policies can be suggested along with the conclusions; First, establishment of green plan-middle and long term environmental goals included in the urban planning to reduce environmental deterioration and pollution. Second, computation of sustainability index-the index is necessary to sustainable urban development, which is related with green GNP of the national level. Third, capacity estimation of nature and social environment-estimation of environmental capacity to the civilized area is required become an ecopolis, and is required to focus on the western area of Pusan which has high degree of potentiality.

낙동강 수계 수질관리를 위한 모델링(2) : 용존산소 수지에 관한 연구 A study on DO balance

박청길,송교욱,안욱성 한국물환경학회 1993 한국물환경학회지 Vol.9 No.1

The Nakdong river that was already over third grade in water quality criteria as BOD. The trophic state was over entrophic and the state of Do level was supersaturation inspite of high organic loads from the each tributary. It was the result of abnormal algal bloom according to the influent of each tributary which had high nutrient concentration. In all stations except Koryong, DO saturation level showed 114.4-160.9%. The model input parameters obtained by laboratory experiment were 0.11-0.49/d in deoxygenation rate(k-1) and 0.31-0.84g/㎡d in sediment oxygen demand(SOD). DO balance was conducted using the enhanced stream quality model(Qual 2E) which was developed by U. S. EPA. The Qual 2E model includes internal sources and sinks of oxygen. The major sources of oxygen, in addition to atmospheric reaeration, are the oxygen produced by photosynthesis and the oxygen contained in the incoming flow. The sinks of DO includes biochemical oxidation of carbonaceous and nitrogenous organic matter, benthic oxygen demand and the oxygen utilized by respiration. Based on the field data, the widely used Qual 2E model was calibrated and verified and then used to DO balance. The calibrated and verified results were in good agreement with measured value within relative error of 17%. In the result of DO balance, the major sources of DO were photosynthetic production and contribution rates of June and August were 71.47 and 48.02%, respectively. The major sinks of DO were biochemical oxidation of carbonaceous organic matter and the rates were 51.54 and 47.67%, respectively.

신성교,박청길,송교욱 한국환경과학회 1998 한국환경과학회지 Vol.7 No.2

This study was conducted to evaluate water quality utilizing principal component analysis in the Nakdong River Estuary. From the results of analysis, water quality in the Nakdong River Estuary could be explained up to 65.3 percentage by three factors which were included in river loading(wastes from the Nakdong River and rainfalls ; 39.1%), sediment resuspension(13.7%) and metabolism(12.5%). In the eastern part of estuary in flowing the Nakdong River, river loading factor score(factor 1)was higher than that in western part. Sediment resuspension factor score(factor 2) was high in shallow water, while metabolism factor score(factor 3) was high in deeper water. For seasonal variations of factors score, factor 1 was highly related to rainfall season.
